Position Your Modem Router

The modem router lets you access your network anywhere within the operating range of your

wireless network. However, the operating distance or range of your wireless connection can

vary significantly depending on the physical placement of your modem router. For example,

the thickness and number of walls the wireless signal passes through can limit the range.

Additionally, other wireless access points in and around your home might affect your modem

router’

s signal. Wireless access points are modem routers, repeaters, WiFi range extenders,

or any other device that emits a wireless signal for network access.

Position your modem router according to the following guidelines:

• Place your modem router near the center of the area where your computers and other

devices operate, and within line of sight to your wireless devices.

• Make sure that the modem router is within reach of an

AC power outlet and near Ethernet

cables for wired computers.

• Place the modem router in an elevated location, minimizing the number walls and ceilings

between the modem router and your other devices.

- Ceiling fans

- Home security systems

- Microwaves

- Computers

- Base of a cordless phone

- 2.4 GHz cordless phone

• Place the modem router away from large metal surfaces, large glass surfaces, and

insulated walls such as these:

- Solid metal doors

- Aluminum studs

- Fish tanks

- Mirrors

- Brick

- Concrete

Cable Your Modem Router

The most common way to cable your modem router is the simplest, without any other routers

or gateways on the same network. You can also cable the modem router to another router or

gateway and log in to the modem router to specify this setting.

Cable the Modem Router in a Simple Network

The modem router comes configured to work as both a modem and a router. You can share

your Internet connection without connecting the modem router to a router or gateway.

 To cable your modem router:

1. Connect a coaxial cable.

Use the coaxial cable that your cable company provides to connect the cable port on the

modem router to a cable wall outlet or a line splitter.

For XFINITY cable Internet service, Comcast XFINITY recommends connecting your

modem router to a cable wall outlet.

2. Connect the power adapter provided in the package to the modem router and plug the

power adapter in to an electrical outlet.

3. Press the Power On/Off button on the rear panel of the modem router.

The Power LED lights green.

You can log in to the modem router to view or change its settings.

Cable Your Modem Router to a Router and Use Bridge Mode

If you want to cable the modem router to a router, then you must log in to the modem router

and change its Router Mode setting. Changing this setting prevents certain network conflicts

that can occur when two devices on the same network perform routing functions such as

network address translation (NAT) and DHCP (assigning IP addresses to devices on the

network). This turns the modem router into a bridged modem

 To cable your modem router to a gateway or router:

1. Connect a coaxial cable.

Use the coaxial cable that your cable company provides to connect the cable port on the

modem router to a cable wall outlet or a line splitter.

For XFINITY cable Internet service, Comcast XFINITY recommends connecting your

modem router to a cable wall outlet.

2. Connect the power adapter to the modem router and plug the power adapter into an

electrical outlet.

The Power LED lights green.

3. On your computer or wireless device, find and select the WiFi network.

The WiFi network name is on the product label.

4. Join the WiFi network and enter the WiFi password.

The password is on the product label.

Your wireless device connects to the WiFi network.

5. Launch a web browser.

6. Type http://routerlogin.net or http://192.168.0.1.

A login window opens.

7. Enter the modem router user name and password.

The user name is admin. The user name and password are case-sensitive.

The BASIC Home page displays.

8. Select ADV

ANCED > Administration > Router Mode.

9. Select the No radio button.

With this setting, the modem router works as a bridge and obtains IP addresses from the

cable Internet provider.

10. Click the Apply button.

Your change is saved.

11. Follow the instructions that came with your router or gateway to connect it to the modem

router.

Activate Your Internet Service
